' Application fiie'e'rsinn 20;

This invention relatesto chip separators of the type. disclosed ,1 in my, prior 1,126,240 issued January 26, 1915. One of the objects-of this invention is to improve my earlier inventioniby adapting it forluse with an automatic feedmechanism. I

A further object of this. invention is .to so design the air' draft exhaust passage that there will be-no back-draft when the waste material is deposited after being separated from the manufactured product. "Another object is to construct'the feeder plates so that the materialwill not'be subjected toairpressure until dropped into the forced ,air draft .15 in order that a solid single blast may action the. material. Further objects and improvenlents will appear in the specification which describes one'embodiment of myinventionl For a more detailed description of the device, I will now refer to my drawings wherein Fig. 1 is a side view of my machine, cut away partially to show a section of the lower and upper Vibratingfeeder plates. Fig.2 is a 7 partially cut away planview of the vibrat- 3 ing feeder plates. Fig. 3is a perspective diagrammatlc drawing of the belt transmission for operating the two feeder plates at different relative speeds from the same power source. Fig. 4 is a side view of my draft control and Fig. 5 is a front view of the same. Referring more particularly to Fig. 1, ref erence numeral 10 indicates abase to which is secured the blower 11, which is operable in any desired way, that is, by an electric moair draft. In order to control this air draft, I employ a blast gate 12 mounted on an operating shaft 13, and controlled by the hand wheel 14. This hand wheel 14 is set with reference to a pointer gauge 15, andacts to regulate the air draft to a degree depending upon the type of material which is to be acted upon.- A set pin 16, mounted in the bearing 17 is adapted to enter various shallow bores 18 in the wheel 14 to hold the same in its set position. It will be noted that I pivot my blast gate at one extremeside of the air chute so that only a single air stream is permitted'to ascend thechute.

mits of better regulation-and"more efficient separation. c

[The material .to'be separated ishandle-d. through a pairof vibrating feeder plates, one ofgtheseplates being shown at'20 and the other, 21.] These platesare .angularly mounted on vibrator rockeraims 22, carried by theside casing plates 23, there being four vice. Each of these feeder plates is covered to with a series of domeshaped obstructions 24 which act to slow up the movement ofthe materialdownward to the discharge end and to spread the materialuniformly over the plate- It will be observed that the feeder plate 20 has a discharge opening 25, resting, just above the second plate 21. Mounted over this discharge copeni ng are a series of fingers 26 adapted to further slow down the movementof the material from the one feeder Pl te tqtheother; i f In order to vibrate these plates, there are two eccentrics numbered 27 and 28-shown in F1 and 3,.theseeccentrics being adapted to vibrate the feed plates tvariei. speeds in anyof the usual standard'w'ays of submitting an eccentric motion. It is? and unnece sary to describe this trainsn sincei't forins no part of he pand is shown'in-niy original Patent 1, referred to supra. V

For a further detailed descripticn ofthev manner of operating'the eccentrics 27 and 28, i The eccentric 27 adapted'to operate the feeder platef21 is mounted on'the shaft-29 carried lnb'earings *80'aiidf 31. The eccentric 28 e rich 26,2 10

45 transmits motion to the shaft 34 and the eccentric 38. It will be observed that by means of this system of pulleys and belts, the eccentric 27 will be operated at-a con siderably lower speed than the blower shaft 11. Moreover, the eccentric 28 will be sub-- jected to an even further reduction in speed, and will consequently operate at a considerably lower speed than the shaft 27-.- Thus,

the vibrating feeder plate will be vibrated at a lower frequency than the secondary vibrating feeder plate 21.

The vibrating plate 21 is equipped with a discharging end 46, this discharging endbeing of solid metal, so that the discharged material will not be actedupon by the air draft until it falls vertically past theopenper;

A screen. 48 the passage prevents any material from dropping int-othe air clinte" In order to obviateiaiiy back 'ares 'surewhich mightbe created by the air draft carrying awaythe waste material, I have adapt d: my

device so-that a continuous exhaust passage rial was deposited. This arrangementcau'sed considerable back draft, especially when the screen became a little clogged with. foreign matter. y r V g H a It will be understood that in operation the material is placed into the initial feeder'plate 20 operating at a slow speed under the influence of eccentric28',the materialbeing fed rated will, of course, drop by gravity on the chute 51 and into some suitable container.

While I have shown one desirable form of my invention, as improved, it should be understood that other forms may occur within the scope of the appended claims. For a more full and detailed description of the invention, 1t may be" expedient to refer to my pr or patent supra, the present specification being. drawn to fully set forth merely the i1nprovement over the same.

2. In a machine of thecla'ss described, a vibrating feeder plate, a second vibrating feed.- e'r plate adapted to receive'material from said first plate, means for vibrating said second plate at a higher speed than said first plate, an airdraf-t and passagetherefor, and a discharge'end for said second'plate-located above said air passageand constructed to prevent ac t l'on' of the air draft on the material until discharged from said plate.

slowly and spread evenly over the plateby 1 the obstructing portions 24. The material then passes from the initial vibrating. plate through the fingers 26 to the secondary vibrating plate 21, operating at a higher speed. There also, it will be slowed up and spread uniformly by. the obstructing portions 2 1 and will finally be permitted to leave through the exit end 46. v

It will then drop by gravity past the opening 47 of the air draft passage 19, whereit will be acted upon by the air draft adjusted to the proper force by the hand wheel 14 in a manner already described. The chips or v waste material will be blown away by the air draft which will escape through theopening 50, while the waste matter is deposited against
